It is a completely reworked version of the one in fpGUI, without external 
dependencies but with serious improvements: the font embedding in the fpgui 
version is, well, rudimentary, so that has been completely reworked, 
it can now embed fonts on-the-fly, without external tools :)

I also made a start of improving memory usage, page caching and made 
the start for compression.

I haven't committed the reworked version yet, but it is nearly complete, 
so you can expect this soon.
